ANSWER ASAP (EXTRAS POINTS) 5.3n + 7.75 = 70.85, What is the value of n?

Around 11.9

Step-by-step explanation:

5.3n + 7.75 = 70.85

First subtract 7.75 on both sides.

5.3n = 63.1

Then divide both sides by 5.3

n=11.9 (I rounded to the nearest tenth.)

here you go!

Step-by-step explanation:

Since time is one year in I = prt then the options below can be used

If you've had Algebra you can use Systems of Equations to solve this problem

x + y = 30,000  for the parts of the Principal

.09x + .08y = 2420  For the rates and total Earnings

Or you can use a substitution knowing your Principal, Rates and Total Earnings

Remember to write the rates as decimals.

First you can put everything in terms of x as follows

x + y = 30,000

y = 30,000 - x

y can be rewritten as 30,000 - x

Using the rates to total earnings we have

.09x + .08(30,000 - x) = 2420

Then just solve for x.
